Why SITRANS TR320/420?
SITRANS TR320/420 rail transmitters deliver accurate, dependable temperature measurement across demanding processes. With universal inputs, HART 7, robust diagnostics, and SIL 2/3 options, they keep lines running and simplify standardization.
Portfolio:
- SITRANS TR320 — universal single‑input transmitter, 4–20 mA/HART, SIL 2/3 option
- SITRANS TR420 — universal dual‑input transmitter with hot backup and drift detection, 4–20 mA/HART, SIL 2/3
Key benefits
Maximize uptime with hot backup
TR420 automatically switches to a second sensor on failure, so measurement continues without data loss or gaps.
Simplify integration with universal inputs
Connect RTD, TC, resistance, or mV sources on a single rail‑mount platform to standardize installations and spares.
Strengthen safety with SIL 2/3 options
Meet functional safety requirements with certified variants and HART 7 support for reliable commissioning and testing.
